you can also use a super saturated salt solution to extract the silver from your rinse bath.
( hypo check is like a strong salt solution .. )
so it makes sense to me that this salt solution would remove unconverted/unused silver
from the print as well. i can't remember what percentage ( 10% just for an example ... ) the salt subbing is
pre-silvering wouldn't the saturated solution have to be 10% ( for example ) to be in equilibrium ?
i hope i am not being too technical, but is there a reason why a super saturated salt solution
can't be used as a regular fixer for a simple silver gelatin emulsion?
i would love to use something if i find myself in a bind ( and patrick gainer also suggested at one point a strong salt bath might work ) ...
